Rogers RO3206 2-Layer 50mil High-Frequency RF PCB with Immersion Gold
1.Introduction of RO3206
Rogers' RO3206 high-frequency circuit materials are ceramic-filled laminates reinforced with woven fiberglass. These materials are engineered to offer exceptional electrical performance and mechanical stability at competitive prices. The RO3206 high-frequency materials were designed as an extension of the RO3000 series, with one distinguishing characteristic: improved mechanical stability.
2.Key Features
Dielectric constant of 6.15 with tight tolerance 0.15 at 10 GHz/23°C
Dissipation factor of 0.0027 at 10GHz
High thermal conductivity of 0.67 W/MK
Low moisture absorption less than 0.1%
Matched to copper CTE in X-axis (13 ppm/°C), Y-axis (13 ppm/°C), and Z-axis (34 ppm/°C)
Strong copper peel strength of 10.7 lbs/in
3.Benefits
Woven glass reinforcement – Improves rigidity for easier handling
Uniform electrical and mechanical performance – Ideal for complex multi-layer high-frequency structures
Low dielectric loss – Enhances high-frequency performance
Low in-plane expansion coefficient (matched to copper) – Suitable for hybrid designs and reliable surface-mounted assemblies
Excellent dimensional stability – Ensures high production yields
Economically priced – Supports cost-effective volume manufacturing
Surface smoothness – Allows for finer line etching tolerances
